Answer:
sonography
Explanation:
"Sonographers, meanwhile, are trained in using sound waves to take images of tissues and organs in the body. These technologists, using specialized equipment, send high-frequency sound waves through the patient’s body. Consequently, echoes bounce off the tissues and organs and a special computer converts the echoes into visual images. For more information on careers in radiologic technology, visit the American Society of Radiologic Technologists’ website. This is a professional organization for people employed in radiation therapy and medical imaging."

Solve Problem 1 on a cold air-standard basis with specific heats evaluated at
300 K.
1. An air-standard Otto cycle has a compression ratio of 9. At the beginning of
compression, 1 = 100 kPa and 1 = 300 K. The heat addition per unit mass
of air is 1350 kJ/kg. Determine
(a) the net work, in kJ per kg of air.
(b) the thermal efficiency of the cycle.
(c) The mean effective pressure, in kPa.
(d) The maximum temperature in the cycle, in K.
Answer:
(a) 774.529 kJ/kg
(b) Approximately 61.2%
(c) 96.816 kPa
(d) The maximum in the cycle temperature is 2655.3 K
Explanation:
(a)The temperature T₂ = T₁ × r^(k - 1)
∴ T₂ = 300 × 9^(1.4 - 1) = 772.467 K
P₂ = P₁×r×T₂/T₁ = 100 × 8 × 772.467/300 = 2059.912 kPa
W₁₂ = Cv × (T₁ - T₂) = 0.717*(300 - 772.467) ≈ -338.76 kJ/kg
The heat added = q₂₃ = 1350 kJ/kg = Cv × (T₃ - T₂) = 0.717*(T₃- 772.467)
1350/0.717 = T₃- 772.467
T₃ = 1350/0.717 + 772.467 = 2655.3 K
T₄ = T₃ × (1/r)^(k - 1) = 2655.3 × (1/9)^(1.4 - 1) = 1102.596 K
W₃₄ = Cv×(T₃ - T₄) = 0.717 × (2655.3 - 1102.596) ≈ 1113.289 kJ/kg
The net work = W₁₂ + W₃₄ = -338.76 + 1113.289 = 774.529 kJ/kg
(b) The thermal efficiency, [tex]\eta _{th}[/tex] = 1 - T₁/T₂ = (1 - 300/772.467) × 100 ≈ 61.2%
(c) The Mean Effective Pressure, MEP = (Net work)/Displacement Volume)
For unity clearance, volume, we have;
MEP = 774.529/(9 - 1) = 96.816 kPa
(d) The maximum temperature, occur at T₃ = 2655.3 K.
Force is the cause of a velocity change
The answer is true. hope this helped
Answer:
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity
Which option identifies what engineers will do to help in the following scenario?
After an explosion on an offshore drilling rig, engineers were called in to take action.
A) Engineers will work to design a rig that will not allow methane to escape and cause fires.
B)Engineers will create a large container to keep the flowing petroleum from entering the water.
C)Engineers will expand the drilling to divert the methane gas.
D)Engineers will work to design a system that will cap off the pipeline and stop the flow of petroleum.
Answer:
D is Correct
Explanation:
D) Engineers will work to design a system that will cap off the pipeline and stop the flow of petroleum.
In the scenario given, an explosion has occurred on an offshore drilling rig, indicating that there has been a catastrophic failure in the system. The first priority in such a situation would be to contain and stop the flow of petroleum to prevent further damage to the environment and ensure safety.
Engineers would be called in to take immediate action and design a system that will cap off the pipeline and stop the flow of petroleum. This might involve designing and installing valves or other mechanical devices that can shut off the flow of petroleum.
Option A is incorrect because preventing methane from escaping and causing fires is not the immediate priority in this situation. Option B is also incorrect because the immediate priority is to stop the flow of petroleum, not to contain it. Option C is not a feasible solution as diverting methane gas would not address the immediate issue of stopping the flow of petroleum.
Engineers will work to design a rig that will not allow methane to escape and cause fires. Thus, the correct option is A.
Thus, An engineer solves issues using math, science, and technology. Engineering is all around us, enhancing the ways that we work, travel, communicate, maintain our health, and have fun.
Engineers transform scientific information into technology, which they subsequently transform into a practical solution or innovation.
All engineers experience a sense of pride and well-being after successfully completing a challenging assignment. Making, designing, and manufacturing valuable goods and services for other people is a career that will enrich your life.
Thus, The ideal option is A.

What characteristics are common to public schools? Check all that apply. require tuition to attend run by a non-government group free to students through grade 12 higher tuition than a private school run by the government funded by the government
Answer:
c, e, f.
Explanation:
I took the test
The characteristics that are common to public schools, are free to students through grade 12, run by the government, funded by the government. The correct options are B, C, and D.
What are public schools?A public school is one that is supported by the government through taxes. Attending a primary or secondary public school is free for all students.
A more educated population has lower unemployment, lower reliance on government assistance programs, and higher tax revenue.
Education is also important in reducing crime, improving public health, and increasing political and civic engagement.
A private school is self-sufficient and generates its own funding from sources such as student tuition, private grants, and endowments. A public school is funded by the government, and all students attend for free.
The characteristics that are shared by public schools are that they are free for students up to grade 12, are run by the government, and are funded by the government.
Thus, B, C, and D are correct options.
